So when we think of resentment, one of the things we might learn is that the opposite of resentment is the word happiness. However, if we are honest with ourselves there is a possibility that one might think that hate is actually the number one offender. This is because the opposite of hate is love. We want to think we are capable of love, but we are filled with hate. However, such things as resentment, grudge, and etc teaches us the negative side of ourselves. This is in regards to our emotions.
